TECHNICAL FIELD

The present disclosure relates to methods and compositions for treating cancer with a diaryl macrocycle in combination with at least one other cancer therapeutic, such as an EGFR inhibitor.

BACKGROUND

EGFR is expressed in several solid malignancies, including NSCLC, HNSCC, malignant glioma and colorectal cancer, and abnormal or deregulated EGFR activity is known to contribute to numerous tumorigenic processes. Lung cancer remains the leading cause of cancer death in industrialized countries. Cancers that begin in the lungs are divided into two major types, non-small cell lung cancer and small cell lung cancer, depending on how the cells appear under a microscope. Non-small cell lung cancer (squamous cell carcinoma, adenocarcinoma, and large cell carcinoma) generally spreads to other organs more slowly than does small cell lung cancer. About 75 percent of lung cancer cases are categorized as non-small cell lung cancer (e.g., adenocarcinomas), and the other 25 percent are small cell lung cancer. For patients with advanced disease, chemotherapy provides a modest benefit in survival, but at the cost of significant toxicity, underscoring the need for therapeutic agents that are specifically targeted to the critical genetic lesions that direct tumor growth (Schiller J H et al., N Engl J Med, 346: 92-98, 2002).

Mutations that lead to EGFR overexpression (known as upregulation) or overactivity have been associated with a number of cancers, including lung cancer, anal cancers and glioblastoma multiforme. Mutations, amplifications or misregulations of EGFR or family members are implicated in about 30% of all epithelial cancers. Consequently, mutations of EGFR have been identified in several types of cancer, and has led to the development of anticancer therapeutics directed against EGFR, using two approaches: (1) targeted monoclonal antibodies (mABs) that prevent the binding of ligands to EGFR, and (2) small molecule tyrosine kinase inhibitors (TKIs) that block the intracellular catalytic activity of the receptor. Protein kinases are key regulators for cell growth, proliferation and survival. Genetic and epigenetic alterations accumulate in cancer cells leading to abnormal activation of signal transduction pathways which drive malignant processes. (Manning, G.; Whyte, D. B.; Martinez, R.; Hunter, T.; Sudarsanam, S. The protein kinase complement of the human genome. Science 2002, 298, 1912-1934). Pharmacological inhibition of these signaling pathways presents promising intervention opportunities for targeted cancer therapies. (Sawyers, C. Targeted cancer therapy. Nature 2004, 432, 294-297).

First generation small molecule HER TKIs include gefitinib (Iressa®) and erlotinib (Tarceva®), both binding reversibly to the EGFR. Gefitinib is indicated in all lines of treatment of advanced NSCLC harboring EGFR mutations in the tumor and erlotinib is indicated as treatment of advanced NSCLC after prior chemotherapy, but in development in all lines of EGFR mutation positive NSCLC. These new drugs reversibly target the EGFR kinase domain.

Second generation small molecule TKIs have been designed as irreversible EGFR inhibitors which bind irreversibly to EGFR kinase domain, preferably to cysteine 797 of EGFR. Despite initial response in patients with EGFR mutations, acquired resistance often develops after a median of approximately 12 months. The consensus definition of acquired resistance includes patients who had previous treatment with a single-agent EGFR-TKI (e.g., gefitinib or erlotinib); either or both of the following: a tumor that harbors an EGFR mutation known to be associated with drug sensitivity (i.e., G719X, exon 19 deletion, L858R, L861Q) or objective clinical benefit from treatment with an EGFR-TKI; systemic progression of disease applying RECIST criteria known in the art, while on continuous treatment with EGFR directed treatment for at least 24 weeks.

Despite the success of the first and second generations of EGFR inhibitors in targeted NSCLC therapies, the duration of clinical response is limited by the inevitable development of acquired drug resistance. In addition to the primary EGFR mutations (associated with erlotinib and gefitinib sensitivity), approximately half of the patients with acquired EGFR-TKI resistance have a second EGFR mutation (T790M) in the ATP-binding pocket of the tyrosine kinase that may alter receptor affinity in favor of ATP. These second mutations enable the cancer cells to continue signaling via mutant EGFR, suggesting that in a proportion of patients with acquired resistance to EGFR-TKIs, tumor growth and proliferation remains dependent on EGFR. Other intrinsic or acquired resistance mechanisms include the upregulation of bypass signalings (such as AXL, MET, ERBb2, etc), activating mutations in the downstream pathways (PI3K, AKT, MEK, RAF), low levels of mRNA or polymorphisms of the pro-apoptotic protein BIM, induction of a transcription programme for EMT and phenotypical changes, or induction of elevated tumour PD-L1 levels. (Morgillo F, Della Corte C M, Fasano M, et al. Mechanisms of resistance to EGFR-targeted drugs: lung cancer. ESMO Open 2016; 1: e000060)

There is a significant medical need in the art for a satisfactory treatment of cancer driven by EGFR. In addition to the single-agent targeted therapies strategies outlined above in first line and for overcoming the non-responsiveness exhibited by resistant cancers, combination treatments may also provide promise.

Embodiments

In some embodiments, the methods described herein relate to the treatment of cancer comprising administering to a patient in need of treatment a therapeutically effective amount of a compound that inhibits FAK, SRC and JAK2 in combination with an EGFR inhibitor. It will be appreciated that an inhibitor is any substance that reduces or suppresses the activity of another substance, such as a cell surface receptor (i.e. a receptor tyrosine kinase), or a kinase (i.e. a non-receptor tyrosine kinase). The definition of an “inhibitor” is well known to one of skill in the art, and the use herein of the general term “inhibitor” is understood to be the usual and customary meaning. It will be appreciated that “a compound that inhibits FAK, SRC and JAK2” is a compound that has affinity for all three of the biological targets FAK, SRC and JAK2.

The Janus family of kinases (JAKs) include JAK1, JAK2, JAK3 and TYK2, and are cytoplastic non-receptor tyrosine kinases required for the physiologic signaling of cytokines and growth factors. (Quintas-Cardama A, et al., Nat. Rev. Drug Discov. 2011, 10(2), 127) Aberrant regulation of JAK/STAT pathways has been implicated in multiple human pathological diseases, including cancer (JAK2) and rheumatoid arthritis (JAK1, JAK3). A gain-of-function mutation of JAK2 (JAK2V617F) has been discovered with high frequency in MPN patients. (Levine R L, et al. Cancer Cell 2005, 7, 387) The mutation in the JH2 pseudokinase domain of JAK2 leads to constitutively kinase activity. Cells containing the JAK2V617F mutation acquire cytokine-independent growth ability and often become tumor, providing strong rationale for the development of JAK inhibitors as a targeted therapy. In addition, hyperactivation of the JAK2/signal transducers and activators of transcription 3 (JAK2/STAT3) is responsible for abnormal dendritic cell differentiation leading to abnormal dendritic cell differentiation and accumulation of immunosuppressive myeloid cells in cancer (Nefedova Y, et al. Cancer Res 2005, 65, 9525). In Pten-null senescent tumors, activation of the JAK2/STAT3 pathway establishes an immunosuppressive tumor microenvironment that contributes to tumor growth and chemoresistance (Toso A, et al. Cell Reports 2014, 9, 75). JAK2 gene fusions with the TEL(ETV6) (TEL-JAK2) and PCM1 genes have been found in leukemia patients. (Lacronique V, et al. Science 1997, 278, 5341, 1309-12. Reiter A, et al. Cancer Res. 2005, 65, 7, 2662-7.) It was reported that JAK/STAT3 signaling pathway was aberrantly increased in EGFR inhibitor-resistant EGFR-mutant non-small cell lung cancer (NSCLC) cells, and JAK2 inhibition overcomes acquired resistance to EGFR inhibitors that support the use of combination therapy with JAK and EGFR inhibitors for the treatment of EGFR-dependent NSCLC. (Gao S P, et al. Sci Signal. 2016, 9 (421):ra33) JAK/STAT3 signaling promotes cancer hallmarks in the tumor and its environment, including proliferation, survival, angiogenesis, tumor metabolism while suppressing antitumor immunity. (Buchert M, et al. Oncogene, 2016, 35, 939-951) Inhibition of cytokine-dependent activation of the JAK/STAT3 pathway with JAK inhibitors may also afford orthogonal treatment opportunities for other oncogene-addicted cancer cells that have gained drug resistance. Focal amplification of JAK2 gene was observed in postchemotherapy triple-negative breast cancers (TNBCs) in a group of 9p24-amplified tumors, suggesting a role in tumorigenicity and chemoresistance. (Balko J M, et al. Sci Transl Med. 2016, 8(334):ra53)

c-Src is a nonreceptor tyrosine kinase. The Src family (SFK) comprises of eight members in humans (Src, Fyn, Yes, Lyn, Lck, Hck, Blk and Fgr) with a molecular weight between 52-62 KDa. Src and its family members are deregulated in many types of cancer. Src is a key downstream transducer of many RTKs, including EGFR, HER2, and c-Met. Activation of Src signaling has been implicated in conferring therapeutic resistance to targeted antiendocrine therapies, receptor tyrosine kinase therapies, traditional chemotherapies, and radiation therapies. (Zhang S, et al Trends Pharmacol Sci. 2012, 33, 122). SRC can promote signaling from growth factor receptors in a number of ways including participation in signaling pathways required for DNA synthesis, control of receptor turn-over, actin cytoskeleton rearrangement, migration, adhesion, invasion, motility, and survival. (Bromann P A, Oncogene 2004, 23, 7957-7968) A prominent role of Src in tumor progression-related events such as the epithelial mesenchymal transition (EMT) and the development of metastasis have been reported through the interaction with the potent metastasis suppressor, N-myc downstream regulated gene 1 (NDRG1), that regulates cancer cell migration by inhibiting Src activity. (Liu W, et al. Oncotarget. 2015, 6: 35522-35541) Although EGFR inhibitors have achieved a significant success in the majority of NSCLC patients harbor EGFR-activating mutations, a subset of patients with EGFR mutations are refractory to EGFR-TKIs. Resistance to EGFR inhibitors reportedly involves SRC activation and induction of epithelial-to-mesenchymal transition (EMT). The primary resistance to EGFR-TKIs is associated with higher levels of CRIPTO1 expression. CRIPTO1 activated SRC and ZEB1 to promote EMT via microRNA-205 (miR-205) downregulation. Recently it was reported that saracatinib, a selective SRC inhibitor, can re-sensitize ALK inhibitor-resistant cell lines, demonstrating a therapeutic role of SRC inhibition in overcoming ALK inhibitor resistance. (Crystal A S, et al. Science 2014, 346, 1480-1486)

Focal Adhesion Kinase (FAK) is a 125 kDa non-receptor tyrosine kinase and plays a significant role in adhesion, survival, motility, metastasis, angiogenesis, lymphangiogenesis, cancer stem cell functions, tumor microenvironment and epithelial to mesenchymal transition (EMT). (Golubovskaya V M, Front Biosci (Landmark Ed).; 19: 687-706) Nuclear FAK controls chemokine transcription, Tregs, and evasion of antitumor immunity, and the small-molecule FAK kinase inhibitor VS-4718 drives depletion of Tregs and promotes a CD8+ T cell-mediated anti-tumor response. (Serrels A, et al, Cells 2015, 163, 160-173). Therefore, FAK inhibitors may trigger immune-mediated tumor regression. FAK is hyperactivated in human pancreatic ductal adenocarcinoma (PDAC) and correlates with immunosuppressive tumor microenvironment (TME). Targeting focal adhesion kinase renders pancreatic cancers responsive to checkpoint immunotherapy by overcoming the fibrotic and immunosuppressive PDAC TME in mouse models. (Jiang H, et al. Nat Med. 2016, Jul. 4 [Epub ahead of print]).

Cell Lines

Human lung adenocarcinoma PC-9 cells, harboring EGFR exon 19 deletion (E746-A750) were provided by F. Hoffmann-La Roche Ltd. with the authorization of Dr. Mayumi Ono (Kyushu University, Fukuoka, Japan). Human lung adenocarcinoma H1975 cells, harboring both sensitizing L858R and resistant T790M mutation, were purchased from the American Type Culture Collection (ATCC). All cell lines were maintained in RPMI (Roswell Park Memorial Institute medium) 1640 supplemented with 1% penicillin/streptomycin/glutamine (Gibco) and 10% fetal bovine serum (FBS) (Gibco) in 5% CO₂, 37° C. cell culture incubator and were routinely evaluated for mycoplasma contamination.

In-Vitro Assays Example 1: Cell Viability Assay

Cells were seeded on 96-well plates at the following densities: 2×10³, 3×10³ and 4×10³ and incubated for 24 hours. Next, the cells were treated with serial dilutions of the drugs administrated at doses typically corresponding to ⅛, ¼, ½, ⅝, ¾, ⅞, 1, 1.5 and 2 of the individual IC50 values. After 72 hours of incubation, 0.5 mg/ml of MTT (tetrazolium-based semiautomated colorimetric 3(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) reagent (Sigma Aldrich) was added to the medium in the wells for 2 hours at 37° C., formazan crystals in viable cells were solubilized with 100 μl DMSO and spectrophotometrically quantified using a microplate reader (Varioskan Flash Thermo Electron) at 550 nm of absorbance. Fractional survival was then calculated by dividing the number of cells in drug-treated wells by the number of cells in control wells. Data of combined drug effects were subsequently analyzed by the Chou and Talalay method (See Chou T C. Drug combination studies and their synergy quantification using the Chou-Talalay method. Cancer research. 2010; 70:440-6). Combination Index (CI) values <1, =1 and >1 indicated synergism, additive effect and antagonism, respectively.

Example 2: Colony Formation Assay

Cells were plated in six-well plates at 1000 cells/well in RPMI, 10% FBS. The cells were cultured for 24 hours and the media were then replaced with RPMI, 1% FBS with or without inhibitors. After 72 hours the media were removed and replaced with fresh media without inhibitors for a total of 10 days. At the end of the experiment, the media were removed and the cells were washed with phosphate-buffered saline (PBS). The colonies were fixed and stained simultaneously with 0.5% crystal violet in 10% of ethanol for 15 min. The stain was aspirated and the wells were washed with deionized water until the background was clear. The wells were then photographed. As a semiquantitative measurement, the crystal violet was extracted from the colonies with Triton X-100 0.5% solution overnight and the absorbance was measured at 570 nm.

Example 3. Enzymatic Kinase Inhibition Assay 1

The enzymatic kinase inhibition against FAK, SRC and JAK2 were evaluated at Eurofins using the Erofins KinaseProfiler™ panel. All compounds were prepared to a working stock of 50× final assay concentration in 100% DMSO. Where appropriate, more concentrated stocks were diluted manually to 50× using 100% DMSO. Compounds supplied as powders were reconstituted to a 10 mM stock in 100% DMSO before further dilution to 50×. The required volume of the 50× stock of test compound was added to the assay well, before a reaction mix containing the enzyme and substrate was added. The reaction was initiated by the addition of ATP at 10 μM concentration. There was no pre-incubation of the compound with the enzyme/substrate mix prior to ATP addition. Data are handled using a custom built in-house analysis software. Results are expressed as kinase activity remaining, as a percentage of the DMSO control. This is calculated using the following formula: (Mean of Sample Counts Mean of Blank Counts)/Mean of Control Counts.

Example 4. Enzymatic Kinase Inhibition Assay 2

The kinase inhibition IC₅₀ was determined at Reaction Biology Corporation (www.reactionbiology.com, Malvern, Pa.) following the procedures described in the reference (Anastassiadis T, et al Nat Biotechnol. 2011, 29, 1039). Specific kinase/substrate pairs along with required cofactors were prepared in reaction buffer; 20 mM Hepes pH 7.5, 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO (for specific details of individual kinase reaction components see Supplementary Table 2). Compounds were delivered into the reaction, followed 20 minutes later by addition of a mixture of ATP (Sigma, St. Louis Mo.) and ³³P ATP (Perkin Elmer, Waltham Mass.) to a final concentration of 10 μM. Reactions were carried out at room temperature for 120 min, followed by spotting of the reactions onto P81 ion exchange filter paper (Whatman Inc., Piscataway, N.J.). Unbound phosphate was removed by extensive washing of filters in 0.75% phosphoric acid. After subtraction of background derived from control reactions containing inactive enzyme, kinase activity data was expressed as the percent remaining kinase activity in test samples compared to vehicle (dimethyl sulfoxide) reactions. IC₅₀ values and curve fits were obtained using Prism (GraphPad Software).

Example 5. NCI-H1975 Lung Cancer Cell Proliferation Assay

Five thousand NCI-H1975 cells per well were seeded in 384 well white plate for 24 hrs, and then treated with Compound 1, AZD9291(osimertinib) or erlotinib, Compound 1 at 1 mM or 3 mM plus AZD9291 or erlotinib in various concentrations for 72 hours (37° C., 5% CO₂). Cell proliferation was measured using CellTiter-Glo luciferase-based ATP detection assay (Promega) following the manufactures's protocol. IC₅₀ determinations were performed using GraphPad Prism software (GraphPad, Inc., San Diego, Calif.). The results were summarized in FIG. 9 and FIG. 10. Although NCI-H1975 lung cancer cell line endogenously expresses EGFR L858R/T790M double mutations, the third generation irreversible EGFR inhibitor AZD9291 demonstrated very partial inhibition of the cell proliferation. We investigated the synergistic effect of Compound 1 in combination with erlotinib or AZD9291 on NCI-H1975 cell proliferation. Compound 1 alone had only partial inhibition activity to NCI-H1975 at high concentration (IC₅₀ 4 μM). A strong synergy was observed with the combination of AZD9291 and Compound 1 AZD9291 potently inhibited NCI-H1975 with an IC₅₀ of 3 nM in the presence of Compound 1 at 3 μM concentration (FIG. 9). The combination caused much complete cell proliferation suppression compared to AZD9291 treatment alone. Because of the presence of T790M mutation in NCI-H1975 cell line, erlotinib is not sensitive to the inhibition of NCI-H1975 cell proliferation, and the IC₅₀ was improved from 6236 nM to 1000 nM when Compound 1 was present at 3 μM concentration (FIG. 10).

Example 6. Immunoblotting for Cellular Kinase Phosphorylation Assays

NSCLC NCI-H1975 cells (harboring EGFR L858R/T790M double mutations) were cultured in RPMI medium, supplemented with 10% fetal bovine serum and 100 U/mL of penicillin/streptomycin. Half a million cells per well were seeded in 24 well plate for 24 hrs, and then treated with Compound 1, erlotinib or AZD9291, or the combination of Compound 1 with erlotinib or AZD9291 for 4 hours. Cells were collected after treatment and lysed in RIPA buffer (50 mM Tris, pH 7.4, 150 mM NaCl, 1% NP-40, 0.5% Deoxycholate, 0.1% SDS) supplemented with 10 mM EDTA, 1× Halt protease and phosphatase inhibitors (Thermo Scientific). Protein lysates (approximately 20 μg) was resolved on 4-12% Bolt Bis-Tris precasted gels with MES running buffer (Life Technologies), transferred to nitrocellulose membranes using Trans-Blot Turbo Transfer System (Bio-Rad) and detected with antibodies targeting phosphorylated EGFR and total EGFR (Sigma), phosphorylated paxillin and total paxillin (Cell Signaling Technology), phosphorylated STAT3 and total STAT3 (Cell Signaling Technology), phosphorylated AKT and total AKT (Cell Signaling Technology), phosphorylated ERK (Cell Signaling Technology) and Tubulin (Sigma). Antibodies were typically incubated overnight at 4° C. with gentle shake, followed by washes and incubation with the appropriate HRP-conjugated secondary antibodies. Membranes were incubated with chemiluminescent substrate for 5 min at room temperature (SuperSignal West Femto, Thermo Scientific). The chemiluminescent images were acquired with a C-DiGit Imaging System (LI-COR Biosciences). The results were summarized in FIG. 11 and FIG. 12. Compound 1 had no inhibition against EGFR phosphorylation and dose-dependently inhibited the phosphorylation of SRC/FAK substrate paxillin in NCI-H1975 cells (FIG. 11). At 1 μM concentration, Compound 1 had minimum inhibition against the phosphorylation of EGFR, AKT and ERK, and significant inhibition against the phosphorylation of STAT3 and paxillin. At 1 μM concentration, AZD9291 had significant inhibition against the phosphorylation of EGFR, AKT and ERK, and minimum inhibition against the phosphorylation of STAT3 and paxillin. At 1 μM concentration, erlotinib had minimum inhibition against the phosphorylation of EGFR, AKT, ERK, STAT3 and paxillin. The combination of Compound 1 and AZD9291 significantly inhibited the phosphorylation of EGFR, AKT, ERK, STAT3 and paxillin leading to the synergy in the antiproliferation of NCI-H1975 cells.
